"Out of the thirty thousand types of edible plants thought to exist on Earth, just eleven—corn, rice, wheat, potatoes, cassava, sorghum, millet, beans, barley, rye, and oats—account for 93 percent of all that humans eat, and every one of them was first cultivated by our Neolithic ancestors."

If the blessings of our political and social condition have not been too highly estimated, we cannot well overrate the responsibility and duty which they impose upon us. We hold these institutions of government, religion, and learning, to be transmitted, as well as enjoyed. We are in the line of conveyance, through which whatever has been obtained by the spirit and efforts of our ancestors is to be communicated to our children.

— Daniel Webster
